Summary

THE EFFECTS OF DIFFERENT STORAGE PROCEDURES (FREEZING AND REFRIGERATION) ON THE ANALYSIS OF NITRATE, PHOSPHATE AND SILICATE IN SEAWATER SAMPLES HAVE BEEN COMPARED. REFRIGERATION OF THE SAMPLES AT 274-275 K (1-3 DEG C) UP TO 6 DAYS WITHOUT PRESERVATIVE, WAS FOUND TO BE THE MOST RELIABLE STORAGE PROCEDURE. FOR PERIODS LONGER THAN 6 DAYS, ADDITION OF CHLOROFORM (0.5-1% V/V) WILL PRESERVE THE SAMPLES FOR MONTHS WITHOUT SIGNIFICANT LOSSES IN ACCURACY AND PRECISION.
